That still doesn't answer the question, what the difference between that and the 4200 paddles (non I presume)
and what's the difference between in the way the paddles work, they're all flappy paddles but some work differently than others ? all I know is that they suit Italian cars and are pretty well BS on anything else, except perhas the SLS
You need throttle blip so you can feel the change and only Italians have it.
slush autos (merc, tiptronic porsches, datsun 370z etc etc etc) have a torque convertor and hydraulic soft gear engagement, it's all slushy and gradually dis/connected.
A human input doing what the box can do for itself.
manual boxes with paddles (M3, 360 etc) have a conventional clutch, with almost no slippage, and positive gear enagagement... a robot changing gear for you. ... not as well as you can do it yourself.
then you also have DSG double clutch systems (Golf, Porsche PDK, 458 etc etc)... the best of both worlds...
